Abstract

PURPOSE
To investigate the ability to determine the postoperative status of macular hole (MH) in gas-filled eyes using swept source optical coherence tomography (SS-OCT).
METHODS
Ten eyes of 10 patients who underwent vitrectomy, internal limiting membrane peeling and gas tamponade for idiopathic MH were included in this study. The macular area was examined using SS-OCT on postoperative days 1, 2 and 30.
RESULTS
MH status was assessed in 6 eyes (60%) on postoperative day 1 and MH closure was confirmed in 5 of the 6 eyes (83%). MH remained closed in all 5 eyes at 1 month after surgery. Only gas-retinal interface was obtained in 4 eyes (40%) and unclosed MH was found in 1 of the 4 eyes (25%) at 1 month after surgery.
CONCLUSIONS
The MH status can be determined using SS-OCT in the early postoperative period even in gas-filled eyes. Confirming early MH closure with SS-OCT can serve as an important guide to significantly shorten the duration of prone positioning while maintaining high closure rates.

  Figure 1. Successful SS-OCT images obtained from patient 4. (A) Preoperative SS-OCT image showed a stage 3 macular hole. (B) SS-OCT image showed the closed macular hole with visible retinal layers including inner segment/outer segment line through complete intraocular gas endotamponade on post-operative day 1. (C) postoperative day 30. SS-OCT = swept source optical coherence tomography.

  Figure 2. Unsuccessful SS-OCT images obtained from patient 8. (A) Preoperative SS-OCT image showed a stage 4 macular hole. (B) Only the hyperreflective line from gas-retinal surface interface was visible in SS-OCT image through complete in-traocular gas endotamponade on postoperative day 1. (C) Macular hole was closed one month after surgery. Complete absorption of intraocular gas was observed. SS-OCT = swept source optical coherence tomography.
